The now 27-year-old went on to become one of the club’s key players as they were crowned Premier League champions that season.

Matic didn’t enjoy the best of campaigns this time around – something that could be said for a number of Blues – but he is still one of the best defensive midfielders in the world and would be an excellent signing for United.

Whether Chelsea would allow one of their better performers to join a potential title rival, however, remains to be seen – particularly after the backlash they faced last summer after selling Petr Cech to Arsenal.
